One of the most popular and cost effective performance upgrades you can make to a Harley-Davidson® motorcycle is to replace the stock exhaust with a set of low restriction, high performance mufflers. The stock exhaust pipes and S&S performance mufflers make a great high performance exhaust system with a low price tag. S&S Slip on mufflers are great for stock displacement engines, and they provide exceptional low end and midrange torque when used with big inch engines. Performance exhaust will enhance the effectiveness of other performance upgrades like carbs, air cleaners, cams, and increased displacement.

Carburetor or fuel injection adjustments are generally not required, but are recommended for best performance.

Exhaust Noise Disclaimer: Unless noted, S&S exhaust components do not meet U.S. EPA noise standards and may be restricted to closed course competition use. Check local noise ordinances before use.
